Andreas Ikonomou (Vasilis Diamantopoulos) was a strict father and a High School teacher which he taught Giorgos (Vangelis Voulgaridis). The latter fell in love with the daughter (and only child) of Andreas, Maria (Zoi Laskari).

An incident in the school results in teacher's being aware of the relationship between his student and his daughter, who has an abortion. In another school incident, a student, called Evangelou, mocks Mr Andreas during the lesson by drawing him with ears of a donkey, causing the teacher's fury and the eventual expulsion of the boy from the school. Then, the same student is lured by some thugs to splash yogurt on his teacher. After his action, the perpetrator is caught by police and has his head shaved and be paraded with a sign reading about his offense.
